【摘要】：目的:探讨MRI多序列联合检查在胰腺癌术前分期的临床应用价值。方法:回顾性分析25例经手术及病理证实的胰腺癌患者的MRI表现,并与手术及病理结果进行对照。所有患者进行T1WI、T2WI、MRCP以及多期动态增强序列检查。结果:I期患者4例,Ⅱ患者12例,III期患者7例,IV期患者2例。胰腺癌Ⅱ期、III期诊断的灵敏性、特异性、准确率、阳性预测值与阴性预测值分别为91.7%与85.7%、92.3%与94.4%、92.0%与92.0%、91.7%与85.7%、92.3%与94.4%。MRI术前分期与术中及病理有较好的一致性(k=0.841),分期准确率为88.0%。结论:MRI、MRCP联合多期动态增强序列检查在胰腺癌的诊断及分期方面具有重要的临床意义。
[Abstract]:Objective: to evaluate the clinical value of MRI multi-sequence combined examination in preoperative staging of pancreatic cancer. Methods: the MRI findings of 25 cases of pancreatic cancer confirmed by operation and pathology were analyzed retrospectively and compared with the results of operation and pathology. All patients were examined by T 1 WIN T 2 W I MRCP and multi-phase dynamic contrast enhanced sequence. Results there were 4 cases of stage 鈪，
